SIGNAL-B LADE CLASP.

Application filed September 17, 1907.

To all whom it may concern:

Be it known that I, HIRAM O. WILLIAMS, a citizen of the United States,residing at Utica, in the county of Oneida and State of New York, haveinvented certain new and useful Improvements in Signal-Blade Clasps; andI do hereby declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in signal bladeclasps and the object of the invention is to produce a simple andefficient means whereby the blades of signals used in block system uponrailroads may be easily removed and replaced, and comprises variousdetails of construction and combinations and arrangements of parts whichwill be hereinafter fully described and then specifically defined in theappended claims.

My invention is illustrated in the accompanying drawings, in whichFigure l is a side elevation of an apparatus having my invention appliedthereto. Figs. 2 and 3 are enlarged detail views of the partsdisassembled. Fig. 4 is an enlarged plan view of one end of thefastening device. Fig. 5 is a side view of the pivotally mountedweighted member. Fig. 6 is an edge view of a modified form. Fig. 7 is aview show ing an integral bolt upon the modified form, and Fig. 8 is aside view of the modified form illustrated in Fig. 6.

Reference now being had to the details of the drawings by letter, Adesignates the standard or post supporting the signal which is commonlyused in block signals upon railways.

B designates a weighted member, preferably of metal, which is pivotallymounted upon the pin C carried by the post. Said member is provided witha recess upon one side of its pivot, as shown clearly in Fig. 2 of thedrawings and designated by letter D, in which one end of the blade E ofthe signal is adapted to be held. I-Ieretofore blades of signals of thischaracter have been held in place by means of a plurality of bolts,preferably siX, thus necessitating a considerable time in the removal ofthe blade and replace- Patented March 3, 1908.

ment of the same, if desired, for repainting or for other purposes, andhence the usual holes already formed in signal blades may be utilized.

F designates a plate having radial arms, of which four are shown in Fig.l to 4 inclusive and a central hole G for the reception of a bolt H isprovided. Projecting from one face of said plate are the pins or tangs,designated by letter K, each of which is adapted to pass throughregistering eyes or apertures formed in the member B and the end of thesignal blade E, and a nut is adapted to be fastened on the end of thebolt H which is passed through the central aperture in the member B andthe blade.

In Figs. 5 to 8 inclusive, I have shown a slight modification of myinvention in which, instead of utilizing a plate having four radialarms, two of the arms are dispensed with forming a plate, designated byletter L, which has two integral tangs or pins L projecting from thesame face thereof and a central aperture 0 for the reception of a bolt.When said modified form is utilized, preferably two of the plates L areutilized which are mounted side by side, as shown in Fig. 5 of thedrawings, with the tangs thereof passing through the apertures in themember B and a central bolt Q is .passed through the plate and itsthreaded end engaged by a bur or nut. 1

In Fig. 7 of the drawings, I have shown a central bolt N as integralwith the plate L and having threaded ends for the reception of the nutN, thus reducing the number of parts incident to the fastening means forholding the blade.

From the foregoing, it will be noted that, by the provision of theclasps or fastening means shown and described, the blade of thesignaling device may be easily and quickly removed by simply looseningthe central nut, thereby enabling a person to readily remove the bladeand replace the same for any purpose.

What I claim to be new is 1. A signal blade clasp comprising, in

2. A signal blade clasp comprising, in combination with a pivotalweighted member, a blade having apertures registering with apertures insaid member, a plate having integral tangs adapted to pass throughregistering apertures in said blade and mem ber, a bolt carried by theplate and extending through the blade and member, and a nut upon saidbolt, as set forth.

3. A signal blade clasp comprising, in combination with a pivotalweighted member, said member having a recess in one face thereof at oneside of its pivot with apertures in the wall thereof, a blade adapted toseat in said recess and provided with an aperture in registration withthe apertures in said member, a plate having integral tangs engagingsaid registering apertures, and means for fastening the plate to saidblade and member, as set forth.

4. A signal blade clasp comprising, in combination with a pivotalweighted member, said member having a recess in one face thereof at oneside of its pivot with apertures in the wall thereof, a blade adapted toseat in said recess and provided with an aperture in registration withthe apertures in said member, aplate having integral tangs engaging saidregistering apertures, a bolt carried by the plate and extending'throughsaid blade and member, and a nut mounted upon said bolt, as set forth.

5. A signal blade clasp comprising, in combination with a pivotalweighted member, said member having a recess in one face thereof at oneside of its pivot with apertures in the wall thereof, a blade adapted toseat in said recess and provided with an aperture in registration withthe apertures in said member, a plate having radial arms, a tangprojecting from each arm and adapted to pass through registeringapertures in the blade and member, a bolt passing through a centralaperture in said plate and also through registering apertures in theblade and member, and a-nut mounted upon said bolt, as set forth.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.

HIRAM O. WILLIAMS.
